ABSTRACT
Background: The clinical manifestations of hypothyroidism are variable, depending upon its cause, duration and severity. The spectrum extends from subclinical to overt hypothyroidism to myxedema coma. A high degree of suspicion is thus required in order to appreciate the clinical manifestation of the disorder to reach a diagnosis. Purpose of this study was to correlate serum TSH level with severity of clinical manifestations and evaluate possible cause of delay in the diagnosis.Methods: A cross section observational and descriptive study for the assessment of severity of primary hypothyroidism at presentation and evaluation of the causes of delay in diagnosis in 86 patients was done from December 2012 to November 2013 in the Department of Medicine, MGM Medical College, Indore, MP, India.Results: Illiterate patients had significantly (p value 0.002) higher TSH values at presentation. 34.8% of patients presented as severe hypothyroidism with TSH value >100 mIU/L. Delay of as much as 7 years was noted. Majority of patients had a delay of around 1 to 3 years in diagnosis. Only 4.6% patients were diagnosed without any delay due to high level of suspicion at presentation.Conclusions: Due to non-specific symptomatology of hypothyroidism diagnosis is often delayed. Therefore, high index of suspicion is required at the physician抯 level and test of thyroid function is available at subsided cost therefore it should be offered to all such patients.
